合作文化与公司税负水平的动态调整

Collaborative Culture and Dynamic Adjustment of Corporate Tax Burden

本文利用2003-2019年沪深A股上市公司构建研究样本,通过关键词词频构造合作文化指标,运用部分调整模型估计目标税负水平,在此基础上考察了合作文化如何影响公司向目标税负水平的调整。检验结果表明:强调合作的公司向目标税负水平的调整速度更快,表明合作文化对公司税负水平的调整具有促进作用。机制检验表明,合作文化通过促进信息沟通和降低代理成本的方式提高调整速度。进一步研究发现,相较于向上调整税负水平(提高至目标值),合作文化对于公司向下调整税负水平(降低至目标值)的促进作用更明显;合作文化对税负水平调整的促进作用在处于税收征管强度较低地区以及处于交通水平发达地区的公司中更明显。本文从税务管理视角为公司推动合作文化建设提供了理论和经验证据。

This paper uses Shanghai and Shenzhen A-share listed firms from 2003 to 2019 to construct the research sample.It constructs collaborative culture by using keyword frequency,and estimates the target level of tax burden by using a partial adjustment model.On this basis,this paper examines how collaborative culture affects the speed at which firms adjust towards their target levels of tax burden.The test results show that firms that emphasize collaboration adjust more quickly to target levels of tax burden,indicating that collaborative culture exerts a promoting effect on the adjustment of the tax burden level.The mechanism test shows that the collaborative culture improves the adjustment speed by promoting information communication and reducing agency costs.Further research shows that compared to the upward adjustment of the tax burden level(increasing to the target value),collaborative culture has a more obvious promoting effect on the downward adjustment of the tax burden level(reducing to the target value).The promoting effect of collaborative culture on the adjustment to the target level of tax burden is more obvious when the level of tax enforcement is low and when the level of transportation is developed.This paper provides theoretical and empirical evidence from the perspective of tax management for firms to promote the construction of the collaborative culture.
